John Tookey: AUT Construction Professor on the latest Commerce Commission report on building materials and more competition - Heather du Plessis-Allan Drive

A construction expert says today's Commerce Commission report on building materials may not shift the dial.

The Commission says the Government should remove barriers to product substitution and wants competition to be a key objective of regulations.

It also suggests information on products should be shared nationally.

AUT Construction Professor, John Tookey says a limited amount can be achieved by a report like this and that regulations won't bring down costs for consumers.
